Very Well Explained, Should Forward This Video to some adamant Consultant for their better understanding 😜

[@TechSystems]

Hahaha... Sure do share🙂

[@juancarlosfernandezmontero7935]

Greetings from Costa Rica.
Easy and well explained.
Keep the good educational videos.

[@TechSystems]

Thanks Carlos for your feedback

[@DriveYorCareer]

really great work sir. full clarity, satiating the student need. Will expect more videos on energy optimization in chillers.

[@somairsarem5652]

Awesome work - commendable - keep it up, you are doing a great job 👏👍🙏🏻

[@TechSystems]

Thank you Somair.

[@Hvacian]

Excellent explanation. right on spot..

Thanks

[@meditationhypnosismedia8707]

Your videos are helping a lot. Thank you for such amazing content.

[@TechSystems]

Thank you

[@realtruth3767]

Great work 👍

[@TechSystems]

Thanks ✌️

[@yokeleetan8525]

also is there a way to limit demand the first chiller when we want to start the second chiller to prevent tripping due to freezing chill water supply temperature in addition to have slow control valves at the chillers?

[@mubbasharkhan1]

very informative video keep up the good works

Thanks

Greeeeeeeeeat, brother
Go on

Thankyou excellent , easy to understand

[@TechSystems]

Glad to hear that.

Can u explain ? Where is use variable primary flow & where is use variable secondary flow

[@polytechnicolas]

Thank you, it was very helpful !

[@mohammedabdullahkhan4264]

Why primary are variable can you explain, I saw every where only secondary is variable

[@TechSystems]

This is a variable primary only design where the primary is variable and secondary is not available. What you saw is a constant primary-variable secondary system.

[@mohammedabdullahkhan4264]

@@TechSystems in this system, if there is no secondary pumps then how it will circulate the water from Ahus

[@TechSystems]

Circulation will be done by the primary pumps. In this system primary pumps are larger and are designed for water circulation through the loads.

[@sekarsankar7606]

very good explanation

[@TechSystems]

Thank You

[@bhatuborane7761]

Why we not able to overpump in dedicated system?? What are the disadvantage.

[@slamatarik712]

That would not be possible if one pump runing already at his maximum speed

[@yokeleetan8525]

this is a good video.. but i have some queries on chiller stopping procedure. by using %RLA, we are assuming similar size chillers are used. secondly, by using

[@akramrz6739]

My doubt is how the water is being supplied into the buildings without any pump? Plz explain

[@TechSystems]

We have primary pumps here which are designed to supply water to the complete building loads.

[@l.crossjr]

Once power is applied to current iso valves, it takes 30 sec to open. Any suggestions on the fix?

[@TechSystems]

You want it to open more quickly?

[@l.crossjr]

@@TechSystems slower. During stage up sometimes it trips the running chiller

[@TechSystems]

Refer to the actuator data sheet. Opening time would be mention there... Compare this time with the data sheet value

Thanks ❣️

Good information, thanks dear

So great

Sir please make video about RO water system also.....
Thank you good luck....!!!!

Sir please Hindi me samjay sare video take achhe se samajh sakain

[@mdwaquaruddin165]

At 100% load flow rate is 2000 usgpm
At 50% load flow rate is 1000 usgpm flows through chiller what is the remaining water of 1000 usgpm flows .where it goes

[@TechSystems]

At 50% load the pumps speed is reduced, so the flow rate is reduced to 1000gpm.

[@mohamedmohideen8053]

@@TechSystems what happens to the remaining 1000gpm in the piping system,.
